Apparatus for injecting soil conditioning fluid

Abstract

An apparatus is provided for injecting a conditioning fluid into a soil foundation. The apparatus is light in weight and easy to handle, performs fixing, moving and boring work while requiring not much time, and is excellent in working performance. The apparatus for injecting the conditioning fluid includes a boring machine for boring the soil foundation and injecting the soil conditioning fluid into the soil foundation for hardening. Magnet fixtures secure the boring machine to a magnetic wall surface supporting the soil foundation or to a magnetic wall surface mounted on a member supporting the soil foundation. Further, a control panel, capable of remotely controlling switch valves for water and conditioning fluid in this kind of apparatus, is formed as a separate body from the apparatus body.

What is claimed is: 
     
       1. An apparatus for injecting a soil conditioning fluid into a soil foundation including: a boring machine for boring the soil foundation and injecting said soil conditioning fluid into the soil foundation for hardening; and   magnet fixture means for securing said boring machine to one of a magnetic wall surface supporting the soil foundation and a magnetic wall surface mounted on a member supporting the soil foundation;   said boring machine including:   a planar base having guide rails on opposite sides thereof and a magnet fixture means for securing said planar base to said magnetic wall mounted thereon;   a movable base mounted on said planar base, said movable base being slidable along said guide rails and able to be secured in a desired position;   a slide base disposed on said movable base and having an axial guide rail extending in a perpendicular direction relative to a plane formed by said guide rails;   a slider engaged with and guided by said axial guide rail of said slide base and reciprocally slidable in said perpendicular direction and a hollow rod rotatably mounted on said slider and having a hole-saw type cutter at a front end thereof, said hollow rod being capable of injecting the soil conditioning fluid from a rear end portion thereof into the soil foundation through said cutter;   first drive means for rotating said hollow rod; and   second drive means for reciprocally moving said slider.   
     
     
       2. An apparatus for injecting a soil conditioning fluid into a soil foundation comprising: an apparatus body having a water tank, a conditioning fluid tank, a pump for feeding at least water and conditioning fluid under pressure, and a switch valve for switching a first pipeline leading from said water tank and conditioning fluid tank to said pump;   a boring machine located at a position spaced apart from said apparatus body and having a hollow rod with a boring device attached at a front end thereof, a front end of said hollow rod being formed with a discharging port for discharging the water and conditioning fluid fed under pressure from said pump, said boring machine and said apparatus body being interconnected by a second pipeline, said boring machine including   (a) a planar base having guide rails on opposite sides thereof and a magnet fixture means for securing said planar base to a magnetic wall mounted thereon;   (b) a movable base mounted on said planar base, said movable base being slidable along said guide rails and able to be secured in a desired position;   (c) a slide base disposed on said movable base and having an axial guide rail extending in a perpendicular direction relative to a plane formed by said guide rails;   (d) a slider engaged with and guided by said axial guide rail of said slide base and reciprocally slidable in said perpendicular direction and a hollow rod rotatably mounted on said slider and having a hole-saw type cutter at a front end thereof, said hollow rod being capable of injecting the soil conditioning fluid from a rear end portion thereof into the soil foundation through said cutter;   (e) first drive means for rotating said hollow rod; and   (f) second drive means for reciprocally moving said slider; and   a control panel, capable of remote controlling said switch valve, formed as a separate body from said apparatus body.   
     
     
       3. An apparatus for injecting a soil conditioning fluid according to claim 2, wherein said control panel is provided with an indicator for indicating a speed of rotation of said boring machine and a regulator for regulating the speed of rotation of said boring machine. 
     
     
       4. An apparatus for injecting a soil conditioning fluid according to claim 3, wherein said apparatus body has a flowmeter disposed therein and adapted to measure a quantity of discharged fluid by said pump and said control panel is provided with an indicator for indicating a value measured by said flowmeter.
